An auxiliary throttle control arrangement (34) is partially housed in and forms an integral part of a handle assembly (42) for a gear shift lever (30). The actuator component of the control arrangement is in the shape and general configuration of a trigger (40). Together, the trigger (40) and handle assembly (42) are ergonomically styled to form fit the hand. The trigger (40) is spring loaded to provide initial resistance to movement and to return the trigger (40) to its original position as applied pressure is released. The trigger (40) is mechanically coupled to a potentiometer device (140) housed in the handle assembly (42). As the trigger position is changed by the vehicle operator, the resulting movement of the potentiometer (140) produces a control signal having a variable output voltage that is used by a control mechanism (160) to change the engine throttle position. Thus, the subject invention provides a secondary method of accelerating an automotive vehicle from a stopped position. This ability to increase engine revolution without the use of the accelerator pedal provides a controlled technique of preventing vehicle roll back. |
